Subverting the racist lens: Frederick Douglass, humanity and the power of the photographic Image

Frederick Douglass, the abolitionist, the civil rights advocate and the great rhetorician, has been the focus of much academic research. Only more recently is Douglass work on aesthetics beginning to receive its due, and even then its philosophical scope is rarely appreciated. Douglass’ aesthetic interest was notably not so much in art itself, but in understanding aesthetic presentation as an epistemological and psychological aspect of the human condition and thereby as a social and political tool. He was fascinated by the power of images, and took particular interest in the emerging technologies of photography. He often returned to the themes of art, pictures and aesthetic perception in his speeches. He saw himself, also after the end of slavery, as first and foremost a human rights advocate, and he suggests that his work and thoughts as a public intellectual always in some way related to this end. In this regard, his interest in the power of photographic images to impact the human soul was a lifelong concern. His reflections accordingly center on the psychological and political potentials of images and the relationship between art, culture, and human dignity. In this chapter we discuss Douglass views and practical use of photography and other forms of imagery, and tease out his view about their transformational potential particularly in respect to combating racist attitudes. We propose that his views and actions suggest that he intuitively if not explicitly anticipated many later philosophical, pragmatist and ecological insights regarding the generative habits of mind and affordance perception : I.e. that we perceive the world through our values and habitual ways of engaging with it and thus that our perception is active and creative, not passive and objective. Our understanding of the world is simultaneously shaped by and shaping our perceptions. Douglass saw that in a racist and bigoted society this means that change through facts and rational arguments will be hard. A distorted lens distorts - and accordingly re-produces and perceives its own distortion. His interest in aesthetics is intimately connected to this conundrum of knowledge and change, perception and action. To some extent precisely due to his understanding of how stereotypical categories and dominant relations work on our minds, he sees a radical transformational potential in certain art and imagery. We see in his work a profound understanding of the value-laden and action-oriented nature of perception and what we today call the perception of affordances (that is, what our environment permits/invites us to do). Douglass is particularly interested in the social environment and the social affordances of how we perceive other humans, and he thinks that photographs can impact on the human intellect in a transformative manner. In terms of the very process of aesthetic perception his views interestingly cohere and supplement a recent theory about the conditions and consequences of being an aesthetic beholder. The main idea being that artworks typically invite an asymmetric engagement where one can behold them without being the object of reciprocal attention. This might allow for a kind of vulnerability and openness that holds transformational potentials not typically available in more strategic and goal-directed modes of perception. As mentioned, Douglass main interest is in social change and specifically in combating racist social structures and negative stereotypes of black people. He is fascinated by the potential of photography in particular as a means of correcting fallacious stereotypes, as it allows a more direct and less distorted image of the individuality and multidimensionality of black people. We end with a discussion of how, given this interpretation of aesthetic perception, we can understand the specific imagery used by Douglass himself. How he tried to use aesthetic modes to subvert and change the racist habitus in the individual and collective mind of his society. We suggest that Frederick Douglass, the human rights activist, had a sophisticated philosophy of aesthetics, mind, epistemology and particularly of the transformative and political power of images. His works in many ways anticipate and sometimes go beyond later scholars in these and other fields such as psychology & critical theory. Overall, we propose that our world could benefit from revisiting Douglass’ art and thought

Of President Barack H. Obama and Others

The election of Barack H. Obama as President of the United States was a significant event in the social and political history of the United States. His election as the first non-white male President has been seen as a sign of the changing racial attitudes of white Americans. Nonetheless, the specter of race and racism haunts his presidency. As the first African American president, he has to show the black community that he has their social, political, and economic interests on his public policy agenda. On the other hand, he cannot appear to be to overtly pro-black without bruising white racial sensibilities. In order to walk this fine line, President Obama has taken a colorblind approach to public policies. He claims that his color-blind public policies will help to uplift all citizens regardless of race, creed, or national origin. Important for this discussion is the claim that race need not be a factor in public policies. There are some doubts about this claim given the history of anti-black racism in the United States. It is argued, herein, that color or race conscious policies are needed to address some of the social and economic problems that besiege the black community. This article utilizes a pragmatic account of race to illustrate why colorblindness in public policies takes an ahistorical and decontextualized view of race and in the long term will hurt the social and economic standing of African Americans in the move to a more perfect union

The Use of Phenomenological Approach in Evaluating Mentorship Preparation Program in South East Scotland

The Nursing and Midwifery Council for the United Kingdom highlighted the importance of the role of the mentor in the development of competence in student nurses and midwives. Veronica Lambert and Margaret Glacken, as well as Zoe Wilkes, suggested that mentors were fundamental to the students’ smooth entry to the practice environment and clinical learning experience. Furthermore, the Nursing and Midwifery Council Standards for Learning and Assessment in Practice identified the requirement by all providers of clinical education experiences for student nurses and midwives to establish local registers of appropriately prepared mentors in practice, together with the development of a new preparation program for mentors. In 2013, the mentorship team within Edinburgh Napier University, which provides the Nursing and Midwifery Council–accredited Mentorship in Practice Preparatio

Motion sickness diagnostic criteria: Consensus document of the classification committee of the Bárány society

We present diagnostic criteria for motion sickness, visually induced motion sickness (VIMS), motion sickness disorder (MSD), and VIMS disorder (VIMSD) to be included in the International Classification of Vestibular Disorders. Motion sickness and VIMS are normal physiological responses that can be elicited in almost all people, but susceptibility and severity can be high enough for the response to be considered a disorder in some cases. This report provides guidelines for evaluating signs and symptoms caused by physical motion or visual motion and for diagnosing an individual as having a response that is severe enough to constitute a disorder. The diagnostic criteria for motion sickness and VIMS include adverse reactions elicited during exposure to physical motion or visual motion leading to observable signs or symptoms of greater than minimal severity in the following domains: nausea and/or gastrointestinal disturbance, thermoregulatory disruption, alterations in arousal, dizziness and/or vertigo, headache and/or ocular strain. These signs/symptoms occur during the motion exposure, build as the exposure is prolonged, and eventually stop after the motion ends. Motion sickness disorder and VIMSD are diagnosed when recurrent episodes of motion sickness or VIMS are reliably triggered by the same or similar stimuli, severity does not significantly decrease after repeated exposure, and signs/symptoms lead to activity modification, avoidance behavior, or aversive emotional responses. Motion sickness/MSD and VIMS/VIMSD can occur separately or together. Severity of symptoms in reaction to physical motion or visual motion stimuli varies widely and can change within an individual due to aging, adaptation, and comorbid disorders. We discuss the main methods for measuring motion sickness symptoms, the situations conducive to motion sickness and VIMS, and the individual traits associated with increased susceptibility. These additional considerations will improve diagnosis by fostering accurate measurement and understanding of the situational and personal factors associated with MSD and VIMSD

A Virtual Look at Epstein–Barr Virus Infection: Biological Interpretations

The possibility of using computer simulation and mathematical modeling to gain insight into biological and other complex systems is receiving increased attention. However, it is as yet unclear to what extent these techniques will provide useful biological insights or even what the best approach is. Epstein–Barr virus (EBV) provides a good candidate to address these issues. It persistently infects most humans and is associated with several important diseases. In addition, a detailed biological model has been developed that provides an intricate understanding of EBV infection in the naturally infected human host and accounts for most of the virus' diverse and peculiar properties. We have developed an agent-based computer model/simulation (PathSim, Pathogen Simulation) of this biological model. The simulation is performed on a virtual grid that represents the anatomy of the tonsils of the nasopharyngeal cavity (Waldeyer ring) and the peripheral circulation—the sites of EBV infection and persistence. The simulation is presented via a user friendly visual interface and reproduces quantitative and qualitative aspects of acute and persistent EBV infection. The simulation also had predictive power in validation experiments involving certain aspects of viral infection dynamics. Moreover, it allows us to identify switch points in the infection process that direct the disease course towards the end points of persistence, clearance, or death. Lastly, we were able to identify parameter sets that reproduced aspects of EBV-associated diseases. These investigations indicate that such simulations, combined with laboratory and clinical studies and animal models, will provide a powerful approach to investigating and controlling EBV infection, including the design of targeted anti-viral therapies

Development and Notch Signaling Requirements of the Zebrafish Choroid Plexus

The choroid plexus (CP) is an epithelial and vascular structure in the ventricular system of the brain that is a critical part of the blood-brain barrier. The CP has two primary functions, 1) to produce and regulate components of the cerebral spinal fluid, and 2) to inhibit entry into the brain of exogenous substances. Despite its importance in neurobiology, little is known about how this structure forms.Here we show that the transposon-mediated enhancer trap zebrafish line Et(Mn16) expresses green fluorescent protein within a population of cells that migrate toward the midline and coalesce to form the definitive CP. We further demonstrate the development of the integral vascular network of the definitive CP. Utilizing pharmacologic pan-notch inhibition and specific morpholino-mediated knockdown, we demonstrate a requirement for Notch signaling in choroid plexus development. We identify three Notch signaling pathway members as mediating this effect, notch1b, deltaA, and deltaD.This work is the first to identify the zebrafish choroid plexus and to characterize its epithelial and vasculature integration. This study, in the context of other comparative anatomical studies, strongly indicates a conserved mechanism for development of the CP. Finally, we characterize a requirement for Notch signaling in the developing CP. This establishes the zebrafish CP as an important new system for the determination of key signaling pathways in the formation of this essential component of the vertebrate brain

Environmental controls, oceanography and population dynamics of pathogens and harmful algal blooms: connecting sources to human exposure

The definitive version was published in Environmental Health 7 (2008): S5, doi:10.1186/1476-069X-7-S2-S5.Coupled physical-biological models are capable of linking the complex interactions between environmental factors and physical hydrodynamics to simulate the growth, toxicity and transport of infectious pathogens and harmful algal blooms (HABs). Such simulations can be used to assess and predict the impact of pathogens and HABs on human health. Given the widespread and increasing reliance of coastal communities on aquatic systems for drinking water, seafood and recreation, such predictions are critical for making informed resource management decisions. Here we identify three challenges to making this connection between pathogens/HABs and human health: predicting concentrations and toxicity; identifying the spatial and temporal scales of population and ecosystem interactions; and applying the understanding of population dynamics of pathogens/HABs to management strategies. We elaborate on the need to meet each of these challenges, describe how modeling approaches can be used and discuss strategies for moving forward in addressing these challenges.The authors acknowledge the financial support for the NSF/NIEHS and NOAA Centers for Oceans and Human Healt

Robotic injection of zebrafish embryos for high-throughput screening in disease models

The increasing use of zebrafish larvae for biomedical research applications is resulting in versatile models for a variety of human diseases. These models exploit the optical transparency of zebrafish larvae and the availability of a large genetic tool box. Here we present detailed protocols for the robotic injection of zebrafish embryos at very high accuracy with a speed of up to 2000 embryos per hour. These protocols are benchmarked for several applications: (1) the injection of DNA for obtaining transgenic animals, (2) the injection of antisense morpholinos that can be used for gene knock-down, (3) the injection of microbes for studying infectious disease, and (4) the injection of human cancer cells as a model for tumor progression. We show examples of how the injected embryos can be screened at high-throughput level using fluorescence analysis. Our methods open up new avenues for the use of zebrafish larvae for large compound screens in the search for new medicines

Challenges in image-guided therapy system design

System development for Image-Guided Therapy (IGT), or Image-Guided Interventions (IGI), continues to be an area of active interest across academic and industry groups. This is an emerging field that is growing rapidly: major academic institutions and medical device manufacturers have produced IGT technologies that are in routine clinical use, dozens of high-impact publications are published in well regarded journals each year, and several small companies have successfully commercialized sophisticated IGT systems. In meetings between IGT investigators over the last two years, a consensus has emerged that several key areas must be addressed collaboratively by the community to reach the next level of impact and efficiency in IGT research and development to improve patient care. These meetings culminated in a two-day workshop that brought together several academic and industrial leaders in the field today. The goals of the Workshop were to identify gaps in the engineering infrastructure available to IGT researchers, develop the role of research funding agencies and the recently established National Center for Image Guided Therapy (NCIGT), and ultimately to facilitate the transfer of technology among NIH-sponsored research centers. Workshop discussions spanned many of the current challenges in the development and deployment of new IGT systems. Key challenges were identified in a number of areas, including: validation standards; workflows, use-cases and application requirements; component reusability; and device interface standards. This report elaborates on these key points and proposes research challenges that are to be addressed by a joint effort between academic, industry, and NIH participants
